ToaZZ whom it may coneerar .Be--it known that 1 WILLI M CANNON, citizen of the United States, residand State of- TeXas', have invented certain new. and; useful Improvements in Outlet Valves for *Elevated Tanks, of following is'a specification. r

This invention relates to an improved outletvilve for elevated water 'tanksor the like and seeks-, among other objects, .to provide a valvdwherein, when the valve is closed, air will beadmitted to the-outlet PipeQ'ofth'etank So that said pipe may be drained; as; avoid; freezing.

The inventionseeks,; as a to provide a-v'alveof piston type and whereinreciprocationro'f the valve in one direction will' serve to' cut oil flow of water through the valve jand coincidently admit air -while,"l when, the valve; is reciprocated in the opposite direction, admittance of air will be stopped and flow of water 'coincidently permitted -1 And the invention seeks, as a still further obj ect, to provide novel eating the valve.

hereinafter.

In the accompanying drawings:

F igure 1 is a' fragmentary sectional view showing my improved valve installed upon a conventional elevated water tank,

Figure 2 is an enlarged longitudinal sectional view showing the valve closed,

Figure 3 is a View partly in elevation and partly in section, showing the'valve open,

Figure 4 is a detail perspective view showing certain parts of the valve disassembled but in proper relative position, and

Figure 5 is a view on the line 5+5 of Figure 2, looking in the direction of the arrows.

Referring now more particularly to the drawings, I have shown my improved valve which the further object,

The valve niay be" composed of a plurality of-rubber or'other suitable discsv of: considerable length without involving un- 16 exteriorlyiofth e tank lOisa bracketcomwhich, asshown, are arrangedup on jtherod 20- to be clampedinabutting relation by the l nuts22- andipreferably, the discs are beveled attheir peripheries; Annular pocketslarel thus defined between the "discs while, due to Y the reduction inthe area of contactoft he: discs with'the valve casing, 'by'the beveling of the discs, the valve may be constructed.-

prising-spaced parallel arms 23 formedat their inner ends with the halves .24: of a split collar surrounding the barrel. The halves of the collar are provided at their ends with ears 25 through which are engaged boltsor other suitable fastening devices 26 clamping the bracket upon the barrel and, preferably, packing strips 27 are employed between the collar and barrel'to prevent mutilation of the threads of the barrel. Near their outer ends, the bracket arms 23 are provided with openings and journaled therethrough is a vertically disposed shaft 28 having a shoulder 29 to coact with the lowermost of said arms for supporting the shaft. The shaft is formed with a crank arm 30 which at its free end, is provided with an eye 31 and connecting said arm with the valve rod 20 is a pitman rod 32. At its ends this rod is formed with offsets 33 one to removably engage through gaskets 14 clamped by the nuts to form a 55 sealed joint between the outlet and the tank. its lower end is a flattened eye 34; and remov- V ably connected to said shaft is an operating rod 35 provided near its upper end with an offset 36 to engage through said eye and at its lower end with a laterally directed handle 37, the rod 35 being of a length to extend from the shaft 28 downwardly to a point near the ground or within easy reach.

As will now be seen in View of the foregoing description, the rod 35 may be grasped and turned for rotating the shaft 28 and reciprocating the valve 19. By turning the rod in one direction the valve 19 may, as shown in Figure 2, be moved to closed position lying at one side of the outlet 12 of the valve casing shutting off flow of Water through the valve casing to the discharge pipe 15 while, coinoidently, air will be permitted to enter through the barrel 16 to the outlet and consequently to the discharge pipe so that this pipe may drain. Freezing such as would occur were the water allowed to stand in the discharge pipe will accordingly be avoided. Likewise, by turning the rod in the opposite direction, the valve 19 may, as shown in Figure 3, be moved to open position lying at the opposite side of the outlet 12 of the valve casing when flow of air through said outlet will be shut off by the valve while water will be permitted to pass through the casing to the outlet and to the discharge pipe. I accordingly provide a particularly simple and efficient device for the purpose set forth and, as will now be appreciated, a valve which may be readily installed in practical use.

Having thus described the invention, what is claimed as new is: V

1. The combination with a tank, of a tubular valve casing open at both ends and having one end extending through a side of the tank and provided between its ends with an outlet leading through they bottom of the tank, a piston valve in said casing consisting of a plurality of disks secured together in abutting relation and in axial alinement and having beveled edges, and means mounted on the outer end of the casing for reciprocating the valve across the outlet of the casing, the valve when at the inner side of the outlet cutting off flow of water from the tank and permitting air to enter through the outer end of the casing and escape through the outlet and when at the outer side of the outlet cutting ofi flow of air and permitting water to enter the inner end of the casing and pass through the outlet.

2. An outlet valve for tanks comprising a tubular valve casing open at both ends and having an outlet between its ends, one end of the casing being adapted to extend through a side of a tank and the outlet be-- ing adapted to extend through the bottom of the tank, a piston valve mounted in the casing and movable across the outlet, a collar'on the outer end of the casing, arms projecting from said collar beyond the end of the casing parallel with the axis of the easing, a shaft journaled in the outer ends of said arms, means for rotating said shaft, a crank on said shaft between the arms having an eye at its end, a stem extending outwardly from the valve and having an eye at its outer end, a pitman having offset ends and having one end engaged in the eye of the crank and its opposite end engaged in the eye of the valve stem, and an operating rod engaged in and depending from the lower end of the shaft.

In testimony whereof I aflix my signature.
